Scattered showers could linger in Los Angeles Tuesday following four straight days of rain — and even more rain is likely on Thursday and Friday.

Sheets of rain pounded the charred hills of Pacific Palisades as police cruisers navigated the slick, debris-strewn roads. Just months after January’s wildfires, Los Angeles faced a new threat: an intense atmospheric river storm that arrived before the landscape could recover.

The NWS urges residents in the affected areas to monitor local forecasts "and be alert for possible Flood Warnings."

Heavy rain and thunderstorms battered Los Angeles County on Monday afternoon. A flood advisory was issued until midnight for a wide swath of northern and western L.A. County.

A storm is dropping rounds of heavy rain on more than 22 million people across Southern California on Saturday.

After a weekend storm brought downtown Los Angeles its wettest November on record, more rain is forecast for Monday, according to the National Weather Service.

A flash flood warning until 7 p.m. has been issued for parts of Los Angeles County, including Santa Clarita, San Fernando and Calabasas.

Though conditions began to improve on Nov. 16, forecasters warned that another storm system is expected to bring more rain on Nov. 17 and 18.
